3 Claims. ((31 259-180) This invention relates to the art of transforming the dusty light pulverulent material as produced, into free flowing, relatively dustless, small aggregates with density of 20 pounds or more per cubic foot and is an improvement over my pending application, Serial No. 259,065, filed February 28, 1939, and now matured into U. 8. Patent 2,311,154, and is a division of applicant's co-pend lng application Serial No. 278,753, filed June 12, 1939, and now matured into U. S. Patent 2,294,022.

An object of this invention is to furnish an apparatus for the pelleting of such pulverulent material as carbon black.

Another object of this invention is to furnish an apparatus which is simple in design and inexpensive to construct'and operate for the pelleting of such materials as carbon black.

Still other objects and advantages of my invention will be apparent from a careful study of the following disclosure. L The operation of the apparatus herein described and claimed may be fully understood on reference to my issued patent, No. 2,294,022, of which this present application is a division.

In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 shows diagrammatically a layout of the apparatus for carrying forward the process,

The apparatus of this invention, that is, the pellet mill proper is shown in more detai1 in Figures 2-5. While the apparatus and construction details are fully described hereinafter, the operation of this pellet mill is fully described in the above said patent.

Figures 2-5 show the detail r the down flow tubes and also show an adjusting arrangement to vary the slope of the hose members. The numeral represents the bottom of the upper feed hopper 20 and is shown in plan in Figure 5. It is of circular shape and stationary with the rubber tubes 2|, 22, 23 and 24 connected to it by means of ball and socket joints 5!, 52, 53 and 54, so that the connection is free to rotate or to change its angular direction. A circular plate 55 is located at the top of the lower hopper. It is circular and of the same diameter as the plate 50 and it is so mounted that it may be rotated by a worm or gear arrangement. The plate 55 has the gear 58 on its outer edge and the gear wheel 51 meshes with the gear Eton the plate 55. A shaft 58 and wheel 59 ggnnect with the gear wheel 51 to turn the plate The delivery ends of the hose are connected into openings near the edge of the plate 55 also by movable joints 60, BI, 62 and 63 except 64, 65, 66 and 6'! represent telescopic joints in addition to the ball and socket joints. The telescopic joints 64, 65, 66 and 61 are of metal but rubber lined and are capable of extension in length of about 4 feet. These helical tubes are so constructed and adjusted in cooperation with the above said telescopic joints and movable joints that the maameter of the helix in which the tubes are ar- For a full and detailed description of thi plant 55 ranged. Any suitable number of such members 69 and 10 are used depending on the distance between and 65. To the edges of 69 and 10 are loosely attached as by a swivel joint, clamps H and 12. By their attachment to the plurality of tubes, these clamps hold the spacing members and '10 in their relative positions.

Plate 55 is arranged to be rotated by the gear mechanism 58,81, 58 and Though probably unnecessary, it is explained that such rotation is not constant but is only a means for adjustment by the operator of the slope of the spiral. To do this the operator may occasionally rotate disc at, for example, one-quarter or one=half revolution. either forward or backward. If he turns it in a direction to increase the number of turns in the helix, the rubber members will have to lengthen and this is the function of the telescopic joints t l, 65, es and 6? with which each of the tubes is equipped. It is noted that four feet or change in the length of tubes is sumcient for all desirablev adjustments in slope when the diameter of the helix is 2 feet and the distance between plates 5b and 55 is 30 feet.

It is to be understood that the form of my invention, herewith shown and described, is to be taken a a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subioined claims.

1 Having thus described my invention, I claim:

1. Apparatus for making granular an agglomerative powder which is fine and dry comprising a container to receive a cyclic stream of free flowing granules, a second container located below the first mentioned container, helical conduit means between the upper and lower containers having a sufiicient angle of slope that the flow of granules fromthe upper container to the lower will be by gravity, and means for adjusting the maintaining the diameter of the helical conduit means substantially constant.

2. Apparatus for making granular an agglomerative powder which is fine and dry comprising a container to receive a cyclic stream of free flowing granules, a second container located below the first mentioned container, extensible helical conduit means between the upper and lower containers having a sufiicient angle of slope that the now of granules from the upper container to the lower will be by gravity, and means for adjusting the angle of slope of the helical conduit means and ior simultaneously varying the length thereof while maintaining the diameter of the helical extensible conduit means substantially constant,
